Detailed ways

The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

1 to 5, an electric vehicle charging pile in this embodiment includes a pile body 1 and a parking space line 2 arranged on the side of an external road. The head and tail of the parking space line 2 are closed on the external road to form a parking space structure. The pile body 1 is arranged on the parking space line 2 and is used for charging the electric vehicle. It is characterized in that: the pile body 1 includes a charging device 11, a license plate detection device 12 and a communication device 13, and the charging device 11 is connected to an external market. The electrical connection is also connected with the license plate detection device 12 and the communication device 13 to receive external commercial power and convert the charging power to charge the external electric vehicle, and also provide power to the license plate detection device 12 and the communication device 13 to drive the license plate detection device 12 and the communication device 13. The device 13 works, the license plate detection device 12 includes a license plate detection camera 121 and a vehicle body sensor 122, the license plate detection camera 121 and the vehicle body sensor 122 are coupled to each other, and the license plate detection camera 121 is coupled with the communication device 13. , the communication device 13 is connected to the external traffic police department in communication to transmit the license plate image to the external traffic police department to determine whether it is an electric vehicle. The camera 121 captures the license plate image and transmits it to the communication device 13. In the process of using the electric vehicle charging pile of this embodiment, the pile body 1 is first fixed on the side of the external road, and then the parking space line 2 is set on the external road close to the road. At the position of the pile body 1, the parking space line 2 here can be realized by the existing paint painting method, and then the charging device 11 in the pile body 1 can be connected with the mains cable buried in the ground, so that it is completed. For the setting of the charging pile, after the setting is completed, the charging device 11, the license plate detection device 12 and the communication device 13 in the pile body 1 will be powered on and start to work, and the vehicle body sensor 122 in the license plate detection device 12 will work first to detect Whether there is a vehicle parked in the parking space line 2, and after the vehicle body sensor 122 senses the vehicle, it will output a signal to the license plate detection camera 121, and the current parking lot is parked in the parking space line 2 through the shooting function of the license plate detection camera 121.
